Very Sturdy, works perfectly!
Balancing our 10,000 BTU unit on the thin metal strip on the window seemed like asking for trouble. The TopShelf AC was the only solidly built, no drilling solution I could find (Spring 2015). The shelf is very sturdy and works like a dream! It's easy to put-in and take out, it doesn't budge when in use, and it folds up flat for winter-time storage. I can't recommend it enough. Additionally, it's very convenient that it requires no tools for installation! I was hesitant to buy it because it wasn't for sale on Amazon at the time and there were no reviews on the internet but this thing is legit!
